STAIR CARPET AND LIKE FASTENING.

Application filed August 31, 1925, Serial No. 53,528, and in Great Britain January 10, 1925.

This invention relates to means for securing in position carpets or other like coverings to stairways. In the fixing of stair carpets, it is usual to employ rods which extend across the carpet at the angles between the treads and the risers of the stairs and are secured by angle brackets such as aregenerally known as stair rod eyes. The present invention appertains to the typein which independent clip arms are arranged to projectover opposite edges of the carpet.

The. invention consists of a bracket provided with a rear cavity and a clip arm with a forked engaging end having an endwise movement upon the bracket into a wedge fit therewith.

The invention is described with reference to the accompanying drawings in which fication on line a. 0. of Fig. 4 showing the employmentof a spring.

Fig. 4 is a transverse vertical section on line (Z. (Z. of Fig. 3.

Fig. 7 is a longitudinal section of another modification on line g. g. of Fig. 8.

Fig. 8 is a transverse vertical section on line It. h. of Fig. 7.

Fig. 9 is a front view of the bracket separately.

Referring to Figs. 1 and 2, an attachment bracket lis adapted-to fit snugly in the corner at the junction of the tread and riser of the stairway, and is formed at the back with an undercut recess or cavity 2 f an angle shape cross sectionally, or of any other suitable shape as required, said recess or cavity being open at the inward end and preferably closed at the outward end by a side cheek 3.

A clip arm or clamping piece 4 is formed or provided at its outward part and at its underside with an outwardly projecting tongue piece or member 5 which is cranked or bent from the back of the clip arm or clamping piece 4 and is longitudinally disposed and laterally spaced therefrom. Said.

tongue piece or member 5 has inclined sides 5 upon its inner face opposlte the rear side of the clip arm for clamping piece 4 corres ondin to the sha e of the recess or cavity P g P 2, or where the recess or cavity is of a differentshape, the tongue piece or member may be of corresponding section to fit the said The clip arm or clamping piece 4 is connected with the bracket .1 by advancing the tongue piece or member 5 into the recess or cavity 2 of the same, and the outward part of the arm upon the front plate of the bracket 1. There is just sufiicient clearance between the clip arm or clamping piece 4 and the tongue piece or member 5 for saidarm 4 to pass over the bracket 1 and engage same with a wedge fit.

1 Onlya single endwise movement of the clip arm or clamping piece in an outward.

Referring now to Figs. 3 and 4,a spring blade or element 6 isattached to the rear of the bracket 1 andextends across the back of the recess or cavity 2. The spring blade or element v6 at its free end is-slightly bent.

The tongue piece or member 5-is preferably,

provided with a notch 7. across it rear side,

or alternatively to a notch, it may bea projection, as will be understood. 7 v

As the clip arm or clamping piece 4 is brought into engagement with the bracket 1,

the. spring blade or element 6'bears against the underside of the tongue piece. or mem- 1 her 5 and snaps into the notch 7 orover the projection of the tongue piece. or -member and thereby securely holds the arm4-to the bracket 1. The construction is otherwise the same as shown in Figs. 1 and 2.

In the modified form shown in Figs. 5 and 6, a spring element 8 is located across the front of the bracket 1 in longitudinal alignment with the clip arm 4'and is bent at its middle or intermediate portion to engage a depression 9 in the underside of the clip arm or any equivalent projection in lieu ofv the said depression, the free ends of the spring element 8 being passed through apertures 10 for connection to the said bracket. The spring element 8 thereby holds the clip arm or clamping piece 4 securely to the bracket.

In the modified form shown in Figs. 7 to 9, the spring element 11 is arranged at the v front of the bracket 1 in a transverse disposition relatively to the clip arm o damp f ing piece 4: and is secured by its ent free ends to said bracket. The springl element 11 engages a cross notch 9 in the lerside of the clip arm l. p G 7 What I claim is l. lestair" carpet or like fastening, co 7 prising a bracket formed with a re 10 cavity, a spring element located at the be of the bracket, and extending across the cavity, and a Eelip arm with a longitudinally extending tongue piece spaced back therefrom, the said; arm having an endwisemovement on to the bracket With the tongue piece entered in the cavity of the bracket and the opposed end of the arm extending over thefront of the same, and with the spring element bearing against the clip arm.
